What is blood sugar and how does it relate to diabetes?

Blood sugar, also known as blood glucose, is a type of sugar in your blood that is used by your body as a major source of energy. Too much glucose in your blood can lead to diabetes.

Blood sugar levels are tested using a blood sample. You may be asked to fast for 8 hours before your blood glucose test.

What Fasting Blood Sugar Levels Mean

Normal Blood Sugar Levels: Up to 100

Prediabetes: 100-125

Diabetes: 126 or higher

What is Diabetes?

Diabetes is a disorder of the metabolism. Most of the food you eat is broken down into glucose to be used by your body as fuel. The glucose requires insulin to help move it from your blood into your cells. In people with diabetes, the body does not produce enough insulin, or the cells do not respond to the insulin that is being produced. Therefore, the glucose stays in the bloodstream instead of going into the cells. So even though there’s plenty of glucose in the blood, it can’t get to the cells, so it passes out of the body when you urinate instead of being used as fuel.

Diabetes and Heart Disease

If you are diabetic, you’re at increased risk of heart disease. In fact, your risk of heart attack is the same as someone who has already had a heart attack. You can reduce your risk of heart disease by controlling your cholesterol levels, especially your triglycerides. Cholesterol can often be controlled by eating a heart-healthy diet and exercising regularly.
